DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to embodiments of the presentdisclosure, examples of which are illustrated in the accompanyingdrawings, wherein like reference numerals refer to the like elementsthroughout the several views. In this regard, the present embodimentsmay have different forms and should not be construed as being limited tothe descriptions set forth herein. Accordingly, the embodiments aremerely described below, by referring to the figures, to explain aspectsof the present description. Terms used herein are for descriptivepurposes only and are not intended to limit the scope of the disclosure.The terms “comprises” and/or “comprising” are used to specify thepresence of stated elements, steps, operations, and/or components, butdo not preclude the presence or addition of one or more other elements,steps, operations, and/or components. The terms “first,” “second,” andthe like may be used to describe various elements, but do not limit theelements. Such terms are only used to distinguish one element fromanother. These and/or other aspects become apparent and are more readilyappreciated by those of ordinary skill in the art from the followingdescription of embodiments of the present disclosure, taken inconjunction with the accompanying drawings.

The words and phrases used herein should be understood and interpretedto have a meaning consistent with the understanding of those words andphrases by those skilled in the relevant art. No special definition of aterm or phrase, i.e., a definition that is different from the ordinaryand customary meaning as understood by those skilled in the art, isintended to be implied by consistent usage of the term or phrase herein.To the extent that a term or phrase is intended to have a specialmeaning, i.e., a meaning other than the broadest meaning understood byskilled artisans, such a special or clarifying definition will beexpressly set forth in the specification in a definitional manner thatprovides the special or clarifying definition for the term or phrase.

For example, the following discussion contains a non-exhaustive list ofdefinitions of several specific terms used in this disclosure (otherterms may be defined or clarified in a definitional manner elsewhereherein). These definitions are intended to clarify the meanings of theterms used herein. It is believed that the terms are used in a mannerconsistent with their ordinary meaning, but the definitions arenonetheless specified here for clarity.

A/an: The indefinite articles “a” and “an” as used herein mean one ormore when applied to any feature in embodiments and implementations ofthe present disclosure described in the specification and claims. Theuse of “a” and “an” does not limit the meaning to a single featureunless such a limit is specifically stated. The term “a” or “an” entityrefers to one or more of that entity. As such, the terms “a” (or “an”),“one or more” and “at least one” can be used interchangeably herein.

At least: As used herein in the specification and in the claims, thephrase “at least one,” in reference to a list of one or more elements,should be understood to mean at least one element selected from any oneor more of the elements in the list of elements, but not necessarilyincluding at least one of each and every element specifically listedwithin the list of elements and not excluding any combinations ofelements in the list of elements. This definition also allows thatelements may optionally be present other than the elements specificallyidentified within the list of elements to which the phrase “at leastone” refers, whether related or unrelated to those elements specificallyidentified. Thus, as a non-limiting example, “at least one of A and B”(or, equivalently, “at least one of A or B,” or, equivalently “at leastone of A and/or B”) can refer, in one embodiment, to at least one,optionally including more than one, A, with no B present (and optionallyincluding elements other than B); in another embodiment, to at leastone, optionally including more than one, B, with no A present (andoptionally including elements other than A); in yet another embodiment,to at least one, optionally including more than one, A, and at leastone, optionally including more than one, B (and optionally includingother elements). The phrases “at least one”, “one or more”, and “and/or”are open-ended expressions that are both conjunctive and disjunctive inoperation. For example, each of the expressions “at least one of A, Band C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “oneor more of A, B, or C” and “A, B, and/or C” means A alone, B alone, Calone, A and B together, A and C together, B and C together, or A, B andC together.

Comprising: In the claims, as well as in the specification, alltransitional phrases such as “comprising,” “including,” “carrying,”“having,” “containing,” “involving,” “holding,” “composed of,” and thelike are to be understood to be open-ended, i.e., to mean including butnot limited to.

Embodiments: Reference throughout the specification to “one embodiment,”“an embodiment,” “some embodiments,” “one aspect,” “an aspect,” “someaspects,” “some implementations,” “one implementation,” “animplementation,” or similar construction means that a particularcomponent, feature, structure, method, or characteristic described inconnection with the embodiment, aspect, or implementation is included inat least one embodiment and/or implementation of the claimed subjectmatter. Thus, the appearance of the phrases “in one embodiment” or “inan embodiment” or “in some embodiments” (or “aspects” or“implementations”) in various places throughout the specification arenot necessarily all referring to the same embodiment and/orimplementation. Furthermore, the particular features, structures,methods, or characteristics may be combined in any suitable manner inone or more embodiments or implementations.

Exemplary: “Exemplary” is used exclusively herein to mean “serving as anexample, instance, or illustration.” Any embodiment described herein as“exemplary” is not necessarily to be construed as preferred oradvantageous over other embodiments.

Wearable devices can be worn on user's wrist and offer convenient accessin very versatile situations and environments. Identification tagsincluding barcode, QR code, or RFID are highly abundant in multipleenterprise environments and require high frequency of interactions tomaintain proper documentation and workflow. Conventionally, mosthandheld scanners require the user to be constantly handling bulky orheavy equipment for a long period of time.

According to one embodiment of the present disclosure, a wearable deviceis provided. In particular, for exemplary purpose only, the wearabledevice in the medical field will be described herein in detail. However,of course, the present disclosure is not limited thereto.

The wearable device acting as a handheld scanner can be a useful tool torecord and maintain a patient's condition. For instance, whenever a usertakes medication, the user can read a barcode label on a medicinecontainer with the wearable device. Thus, a memory coupled to thewearable device can store detailed information of time, location,frequency, and contents therein so that it enables to keep track of thepatient's medical record.

Furthermore, the wearable device can provide an alarm for how often theuser needs to take one or more doses of a plurality of mediccations,over a span of hours and days, and the wearable device can keep track oftimes the dosages are taken. Thus, where a person is required, forreasons of health, to take a variety of medications at differing timesof the day or night, then it can be easily performed with the wearabledevice according to the present disclosure with a simple program.

The wearable device as a handheld scanner is convenient in regards toaiming, handling, and repositioning the barcode scanner light to insurethat all angles and ranges are available for the user to scan with ease.The conversion between a wearable device and a handheld one allows theuser to carry the scanner hands-free without the need to hold it, aswell as have quick access to it in any moment of need.

With reference now to FIG. 1, there is depicted a block diagram of two(2) independent computing devices “10” and “20,” and two (2) wearabledevices 100 and 200 that are presented for only exemplary andexplanatory purposes as similar pairs of a first computing device 10 anda first wearable device 100, and a second computing device 20 and asecond wearable device 200. For the purposes of this application, a“computing device” is to be interpreted broadly as including amongothers standard personal computers, smart phones, notebooks, tablets,“iPod”, “iPad”, similar Android or iOS devices, and any type of wearabledevice having user interface. Obviously, more than two independentcomputing devices can be employed in accordance with the presentdisclosure.

First and second wearable devices 100 and 200 are now described ingreater detail in which the same units digits and tens digits are usedto identify the same components in each wearable device 100 or 200.However, only first wearable device 100 is described further herein, butit is understood that second wearable devices 200 have the same type ofcomponents that are identified by the same units digits and tens digits.

Referring to FIG. 1, the first wearable device 100 can be comprised ofat least one of a wrist band unit 110, a network unit 120, a displayassembly 130, a control unit 140, a reader 150. Wrist band unit 110 isdesigned to be worn on the wrist of a user. Wrist band unit 110 isdescribed in greater detail with respect to FIGS. 2A, 2B, 2C, 2D, 3A,3B, 3C, and 3D.

Wrist band unit 110 can be made of any flexible material, preferably apolymer plastic, but could also include a standard plastic, leather, anda shaped metal band or linked metal band. In some embodiments, wristband unit 110 can have a length adjustable feature. For example, eachends of wrist band unit 110 can include a conventional detachablemetal/plastic block (not shown) or a conventional magnetic block (notshown) to adjust the length.

Network unit 120 is configured to communicate with other devices.Network unit 120 can be, for instance, disposed at display assembly 130.Display assembly 130 can include control unit 140 as well. Displayassembly 130 can include at least one reader 150. Reader 150 isconfigured to scan either barcode, QR, or a Radio FrequencyIdentification (“RFID”). Reader 150 will be described later in detail.

Network unit 120 can be disposed at display assembly 130. Operationally,network unit 120 is comprised of at least one of a wireless and/orBluetooth communications transceiver unit 122, a NFC (Near FieldCommunication) unit 124, an internet connection unit (not shown), or aGlobal Positioning System (GPS) unit (not shown). In general, networkunit 120 is a communication unit that can wirelessly communicate withfirst computing device 10. For instance, network unit 120 cancommunicate with the first computing device 10 using a Bluetooth orinternet connection unit (not shown) including Long-Term Evolution (LTE)or Wifi. Network unit 120 can also communicate with another wrist bandunit 210 within a second wearable device unit 200, for instance, byusing an NFC device.

For conventional practical reasons, network unit 120 can utilize highfrequency electromagnetic radiation, but it is also possible to use, forexample, a line-of-sight mechanism such as infrared signals (as used inmany television remotes), or to use sonar or lower frequency radiation.In addition, in an alternative embodiment, a communications unit caninclude a unit for wirelessly accessing the Internet, or othercommunication network, and/or to a satellite.

Display assembly 130 can be mounted on wrist band unit 110. Displayassembly 130 can include a conventional LCD or LED display, and caninclude a touchpad or panel. Control unit 140 includes a processor 142programmed and connected to deliver commands and receive informationfrom display assembly 130, and network unit 120.

Reader 150 is coupled to control unit 140. Reader 150 is configured toread at least one of a barcode, a QR code, or RFID.

Reader 150 can be a barcode reader. A barcode is an opticalmachine-readable representation of data relating to the object to whichit is attached. Barcodes systematically represent data by varying thewidths and spacings of parallel lines, and may be referred to as linearor one-dimensional (1D). Later two-dimensional (2D) codes weredeveloped, using rectangles, dots, hexagons and other geometric patternsin two dimensions, usually called barcodes although they do not use barsas such Barcodes can be scanned by reader 150, optical scanners.

Reader 150 can be a QR code reader. QR code (abbreviated from QuickResponse Code) is the trademark for a type of matrix barcode (ortwo-dimensional barcode). A barcode is a machine-readable optical labelthat contains information about the item to which it is attached. A QRcode can, for instance, use four standardized encoding modes (numeric,alphanumeric, byte/binary, and kanji) to efficiently store data.

Reader 150 can be a Radio Frequency Identification (RFID) reader havingan antenna, and an image capture device coupled to at least one of thereaders and the antennae. Radio Frequency Identification (RFID) systemsare of use in many different areas. For example, RFID systems can beused to track goods as they move throughout the supply chain. A RFIDsystem includes reader 150, at least one RFID tag affixed to an item ofinterest and, a computer system coupled to reader 150 to process data.RFID tags include memory that stores data concerning the item to whichthe RFID tag is attached. For example, an RFID tag may be attached to aproduct or a product's packaging such as the packaging for a drill. TheRFID tag attached to the drill's packaging can store a productidentification code that uniquely identifies the item. Reader 150 sendsinterrogation signals to RFID tags and receives responses from the RFIDtag. Reader 150 can be handheld. Reader 150, depending on the needs ofthe end user and the capability of the RFID tags, can read data from theRFID tag and/or write information to the RFID tag. In the examplediscussed above, reader 150 can be used to read the productidentification code from the RFID tag attached to the packaging of thedrill. The computing device receives data from reader 150 and can thenstore, process or otherwise use the collected data. In the examplediscussed previously, the computer system can receive the productidentification code from reader 150 and then use the productidentification code in conjunction with a database program to retrievepricing information for the drill. The pricing information can be sentback to a device that is part of the computer system. For example, thepricing information may be sent to a point-of-sale (POS) system. Whiletypical RFID systems, with handheld or a fixed reader 150, are ideal inmany circumstances, but they have drawbacks. For example reader 150 canbe cumbersome to use. Also, RFID systems require a user to point thereader 150 at different tags. The repetitive nature of pointing andactivating reader 150 can be tiring to individual users. Regarding RFID,the U.S. non-Provisional application Ser. No. 10/931,462, filed 31 Aug.2004, is incorporated by reference herein in its entirety.

With reference to FIGS. 2A and 2B, first wearable device 100 is depictedin greater detail in a presently preferred embodiment. FIG. 2A is aperspective view of the wearable device 100 in a first mode according toone embodiment of the present disclosure.

After the user switches the screen,first dependent screen 172 becomes visible, and the other screens 170,174, 176, and 178 become invisible or hidden, as depicted in FIG. 20B.The user can return back to home screen 170 by dragging his finger ondisplay assembly 130 in a direction of arrow 172B. Display assembly 130can be configured to include a setting that switches a pending screen toeither home screen 170 or any specific dependent screens 172, 174, 176,and 178. For example, display assembly 130 can be configured to switchscreens according to the type of inputs by fingers. If the user taps thescreen twice with two fingers, then display assembly 130 can switch thescreen back to home screen 170. If the user taps the screen thrice orthree times with three fingers, then display assembly 130 can switch thescreen to third dependent screen 176. If the user taps the screen fourtimes with three fingers, then display assembly 130 can switch thescreen to fourth dependent screen 178. Although the exemplary of thepresent screen displays of the disclosure have been disclosed forillustrative purposes, those skilled in the art will appreciate thatvarious modifications, additions and substitutions are possible, withoutdeparting from the scope and spirit of the disclosure.

In summary, to switch modes of home screen 170, the user drags his orher finger from top downwardly on display assembly 130 and obtainssecond dependent screen 174A, as depicted in FIG. 20C. Second dependentscreen 174 becomes visible, and other screens 170, 172, 176, and 178become hidden or invisible. The user can return back to home screen 170by dragging his finger on display assembly 130 in a direction of arrow174A. For example, in a preferred embodiment, as depicted in FIG. 20A,different screen can be selected from a pending screen by swiping eithervertically or horizontally in a direction of an arrow 170A.

With reference now to FIG. 21, a diagrammatic illustration of aninterface screen between first computing device 10 and first wearabledevice 100 (see FIG. 1) is illustrated. An interface of acti-blockcomputer program includes a plurality of buttons on the screen ofcomputing device 10. Acti-block computer program provides a SocialNetwork Service which is a platform to build social networks or socialrelations among people who, for example, share interests, activities,backgrounds, or real-life connections. FIG. 21 depicts a user interfaceof acti-block computer program screen on computing device 10 such as asmart phone or iPod. Acti-block computer program interface includes alogo and home page button 202, a biographic information button 204, aphoto album button 206, a message button 208, a grouping informationbutton 210, a notification button 212, acti-block 214, and a statisticsbutton 216, a status update button 218, and control panel tab 220.

Logo and home page button 202 shows a logo of a company and when pushedor tapped by the user, switches the screen to a home screen. Biographicinformation button 204 includes a link to a profile information of theuser. Photo album button 206 has a link to a plurality of photographsand photographic information that the user or his or her friends haveuploaded or shared. Message button 208 is conventionally configured tosend and receive a message to a friend.

Grouping information button 210 includes conventional algorithms basedon tags or common factors. For example, when the user updates hisprofile or photos, he or she can create and update related tags as well.If the user is interested in a basketball game, grouping informationbutton 210 can display any relevant information related to thebasketball game as a result of a search based on the tags. Postingupdates button 210 shows any updates the user or the user's friends maderecently. Notification button 212 shows any new message from anothercompatible user, an email invitation, a listing of friends, and updateson comments. Acti-block 214 is configured to update data according toinputs from first wearable device 100. Acti-block 214 is configured tohave a calendar-like function which displays dates.

Acti-block 214 is configured to be connected and be updated byactivities of first wearable device 100. For example, if the userwearing first wearable device 100 runs 4 miles, then the distanceinformation received from first wearable device 100 is transferred tocomputing divide 10 and acti-block 214 is updated with such informationautomatically. In this way, acti-block 214 can contain any activityinformation received from first wearable device 100. Such activityinformation can contain calories, kind of food the user had, budget,list of groceries, profile of friends the user met and any otheractivities conducted on daily bases. For example, the user can scanseveral items the user bought with a help of a scanner disposed in firstwearable device 100 and first wearable device 100 can calculates theprice of the items bought and deduct the price of the items from thepredetermined monthly budget. Thus, first wearable device 100 cancalculate and transfer the information to the acti-block computerprogram such that the actiblock computer program can display theinformation such as remaining available funds for the month. Statisticsbutton 216 is configured to show statistics of activities performed inthe acti-block computer program. For instance, statistics button 216 canshow the calories the user burned for the last one month, a distance theuser has walked for the last one month or a monthly budget historycalculating and displaying a budge surplus and deficit based on theinformation the first wearable device 100 scanned. Status update button218 shows any new updates. Control panel tab 220 can be configured tocreate new tabs according to the user's needs such that the user cancontrol and organize his events. A support tab 222 can be configured todisplay any contact information of the user's friends, any help message,problem reports or the like in a conventional manner.

According to a predetermined setting, first wearable device 100 cantransfer information either to another second wearable device 100 (seeFIG. 1) or to computing device 10. With reference now to FIG. 22, asubroutine for determining where to transfer input information isdepicted. The subroutine begins at a start terminal 310 and proceeds toa step 320 where input information and data to first wearable device 100is obtained. From step 320, the process proceeds to a decision step 330where it is determined if the type of input is for an NFC device. If theinput is for an NFC device, then the program proceeds to a decision step340 where a determination is made if a second NFC device is detected,such as second wearable device 100 (FIG. 1). If it is not detected, thenthe program repeatedly loops to the top of decision step 340 until thesecond NFC device is detected. However, if decision step 340 determinesthat an appropriate NFC device is detected, than the program proceeds tostep 350 in which the information is transferred to the second NFCdevice, and then the program terminates in terminal 360. However, ifdecision step 330 determines that the input is not for an NFC device,then the program branches to a decision step 370 where it is determinedif the type of input is for a Bluetooth device. If the input is for aBluetooth device, then the program proceeds to a decision step 380 wherea determination is made if a Bluetooth device is detected, such ascomputing device 10 (FIG. 1). If it is not detected, then the programrepeatedly loops to the top of decision step 380 until the Bluetoothdevice is detected. However, if decision step 380 determines that anappropriate Bluetooth device is detected, then the program proceeds tostep 390 in which the information is transferred to the Bluetoothdevice, and then the program terminates in terminal 360. It can bepredetermined whether the type of input is for a Bluetooth device or fora NFC device as demonstrated in FIG. 22.

With reference now to FIG. 23, there is presented a table 390 listingthe type of wireless inputs and outputs to and from first wearabledevice 100 using either Bluetooth or NFC signals as an exemplary. Ingeneral, Bluetooth signals are used when there is a greater distanceinvolved, such as from first wearable device 100 to a computing device10, such as a smart phone. NFC signals are used where the distance isrelatively small, such as from one first wearable device 100 to anothersecond wearable device 100 in close proximity thereto (see FIG. 1).Table 390 shows that a GPS signal and information can be sent from firstcomputing device 10 to first wearable device 100 and from first wearabledevice 100 to smart phone by a Bluetooth signal. Similarly, Bluetoothsignals are sent to and received by first wearable device 100 to carrybarcode and QR code information, and/or motion information detected fromfirst wearable device 100. On the other hand, business card stored inmemory unit 162 can be communicated upon command to a nearby wearabledevice, such as second wearable device 100 by NFC signals.

With reference now to FIG. 24, a subroutine for calculating caloricconsumption is depicted. The subroutine begins at a start terminal 410and then proceeds to a process step 412 to scan a barcode of food that auser will be ingesting. Should the computing capacity at the wearabledevice be limited, the computing process can be executed at computingdevice 10 instead of or in addition to that at first wearable device100. The subroutine proceeds to a decision step 414 where it isdetermined if the user has preset first wearable device 100 to calculatethe calories of the food. If the setting is preset in that way, then thesubroutine proceeds to process step 416 in which a calculation of thetotal calories consumed is made. From step 416 the subroutine thendetermines in process step 418 the amount of calories burned throughexercise by using information about the exercise that is stored on firstwearable device 100. In process step 420, the calorie information issent to computing device 10 in a first computing device 10. In step 422,the acti-block 214 (see FIG. 21) that contains cumulative calorieinformation is updated, and the subroutine ends at termination terminal424.

If in decision step 414 it is determined that there is no setting thatthe calculation is executed on wearable device, then the programbranches to a second decision step 426 where it is determined if a firstcomputing device 10 is present. If it is found that there is no firstcomputing device 10 present, then the program loops back to the top ofdecision step 414. If there is a first computing device 100 present,then the program proceeds to a process step 428 where a calculation ofthe total amount of calories of the selected food is made at firstcomputing device 10. The program proceeds to process steps 430 and then432 where the caloric information in the smart phone is updated, andalso sent to first wearable device 100, respectively. Then beforeexiting the subroutine at termination terminal 570, the program updatesfirst dependent screen 172 (See FIGS. 20A, 20B, and 20C) on firstwearable device 100 in step 434.

With reference now to FIG. 25, a subroutine is disclosed to determinehow much exercise a user has had. The subroutine begins in startterminal 510 and proceeds to a process step 620 where the motion of auser is recognized and a determination is made as to what type of motionit is. In the present embodiment, the motions being tracked are those ofthe wrist on which first wearable device 100 is being worn. But becausemotion of the wrist and arm of the user will be in synchronization withother motions of the body of the user, such as in running or walking, afairly accurate determination can be made as to the type of motion beingdone. For example, by determining the velocity and acceleration of anarm being swung, it can be determined if the user is walking or running.Since the distance can be determined by motion detectors 118 and 119 (bydouble integrating the measured acceleration), and using the elapsedtime, the speed of motion can be determined and the amount of calories,for example, can be determined. Thus, the program proceeds from processstep 520 to a decision step 530 where it is determined if the detectedmotion is one of a predetermined type of motion. If it is not, then theprogram loops back to the top of step 520 and awaits the recognition ofa motion of the user. If the detected motion is of a predetermined type,the program branches to process step 540 where a calculation of thenumber of motions is made. The subroutine then proceeds to process step550 and then process step 560 where the motion information is sent tofirst computing device 10 where the number of steps taken are calculatedand the information stored, respectively. From step 560 the subroutineterminates in termination terminal 570.

With reference now to FIGS. 26 and 27, a process of transferring socialinformation between a first user of a wearable device (e.g. 100) to asecond user of a wearable device (e.g. 200), as depicted in FIGS. 1 and27, is depicted in the disclosed subroutine and hardware block diagram.The social information can be for example information that is containedon a business card. This would include such information as name, title,business or company name, business address, business telephone andfacsimile numbers, email address, Skype name and Instant Messenger name.This information is stored in a signature barcode 114 or in wearabledevice memory unit 162 through an earlier input operation from firstcomputing device 10 or other computer connection. It can also beobtained from a social media network web sites such as Facebook, Linkin,and Twitter.

The subroutine of FIG. 26 begins in start terminal 610 and proceeds tostep 620 where the signature barcode 214 of second wearable device 100(of the presumed second user) is read by the barcode scanner 113 offirst wearable device 100 of the first user. Then the program proceedsto process step 630 wherein the signature barcode information is savedon first wearable device 100. From step 630, the program proceeds to adecision step 640 wherein it is determined if the computing device 10 ofthe first user can be found. If no first computing device 10 can befound, the program loops back to the beginning of step 630. If a firstcomputing device 10 is detected, the program proceeds to process step650 where the signature barcode information is sent to computing device10 of the first user. Then the program proceeds to process step 660wherein the barcode information is sent to the server 700 (FIG. 27).From server 700, the new “friend” is added to one or more appropriatesocial networks, or a network provided by the present disclosure. Fromstep 660, the program proceeds to process step 670 and then totermination terminal 680. In process step 670 server 700 verifies andauthenticates the information and adds the second smart phone user 200to the wearable device of the friend.

The schematic of a hardware configuration that illustrates the operationof the subroutine in FIG. 26 is depicted in FIG. 27. Barcode scanner 113of the first user reads the signature barcode 214 of the second wearabledevice 100 of the second user through a scanning process. First wearabledevice 100 is connected through a Bluetooth connection to the firstcomputing device 10 of the first user, which in turn is connected by aninternet connection (e.g. a wireless connection) to a server 700. Server700 uploads the information to a designate web site. Obviously, server700 is representative and could include other well known alternatives,such as cloud computing.

With reference now to FIG. 28, a subroutine that implements a level ofsecurity is depicted. The subroutine starts in start terminal 710 andproceeds to a decision step 720 where the presence of an NFC (Near FieldCommunications) device is determined. An NFC device is one thatcommunicates to another NFC device using weak electromagnetic radiationand the NFC protocol over a very short distance from actual touching toa few inches. A smart phone uses NFC to communicate such information asbusiness cards, photographs, and small files to another smart phone. Ifan NFC device is detected, the program branches to a second decisionstep 730 which inquires if the NFC device detects a predeterminedsignal. One such signal can be a password or predetermined gestures suchas handshake. If an NFC device is not detected, the program loops backto the top of decision step 720 to await the receipt of an indicationthat an NFC device is present. In a similar manner, if a predeterminedsignal is not detected in decision step 730, the program loops back tothe top of decision step 730. If a predetermined signal is detected, theprogram proceeds to a process step 740 where a predetermined function isperformed. An example of such a function would be to check that atransmitted password is acceptable and to allow communication betweenthe two devices. From process step 740 the program exits the subroutinethrough a termination terminal 750.

A multi-use for a first wearable device 100 utilizing the same oruniversal key or password for several different types of devices isdepicted in FIG. 29. first wearable device 100 is bidirectionallyconnected using Bluetooth to a first computing device 10, which could inalternative embodiments also be a general purpose, programmed computersystem. In addition, first wearable device 100 is bidirectionallyconnected using NFC, a scanner or Bluetooth to one of several types oftransceivers. For example, wearable device is shown connected to atransceiver 810 that operates a door, to a transceiver 820 that controlsseveral functions of an automobile (e.g. rolling down the windows,starting the car, or turning on the heat or air conditioner), and to atransceiver 830 that controls the operation of a copier. Thus, each ofthese devices can be controlled by a single wearable device code. Eachof transceivers 810, 820, and 830 is bidirectionally connected usingwireless network to a server 30, which is also bidirectionally connectedusing Bluetooth to first computing device 10. The user can use firstwearable device 100 as an universal key for several different types ofdevices. In a case that the user lost first wearable device 100, theuser can change the password for first wearable device 100 on server 30.

With reference now to FIG. 30, a subroutine for monitoring a wearabledevice is depicted. The subroutine begins in a start terminal 910 andimmediately goes to a decision step 920 that determines the time fromthe last status signal to the present and determines if a signal fromwearable device is more than a predetermined amount. If the minimum timesince the last signal is longer than a predetermined amount, the programproceeds to a process step 930 in which computing device 10 or firstwearable device 100 sends a warning signal to a server. The program thenproceeds to a process step 940 in which the user's password is reset orchanged, and then to termination terminal.

With reference to FIG. 31, a subroutine for voluntarily or manuallychanging a password is depicted. The subroutine begins in a startterminal 1010 and immediately goes to a decision step 1020 where a userhas voluntarily changed a password on first computing device 10. Theprogram then proceeds to a process step 1030 in which start phone 10sends the changed password to first wearable device 100. From step 1030the program proceeds to a process step 1040 in which the user is givenan opportunity to display the new password in a pre-determined manner,such as a barcode or a QR code. The program then terminates in atermination terminal 1050. Thus, first wearable device 100 can display abarcode or a QR code on display assembly 130 so that the barcode scanner213 of another second wearable device 100 can read and scan the barcodeor QR code on the wearable device's 100 display assembly. According tothe present disclosure, first wearable device 100 does not need to carrya physical barcode or QR code.

According to a predetermined setting, first wearable device 100 cantransfer information either to another second wearable device 100 (seeFIG. 1) or computing device 10. With reference now to FIG. 32, asubroutine for general procedure for operating a wearable device isdepicted. The subroutine begins at a start terminal 1110 and proceeds toa step 1120 where the processor receives an input from a wrist band unitof the wearable device or a signal from a first portable network device.From step 1120, the process proceeds to a decision step 1130, wherecontrol unit 140 (FIG. 1) determines whether the input or the signal isa predetermined type. From step 1130, the process proceeds to acommunication step 1140, where a network unit communicates with at leastone of the first portable network devices, a second portable networkdevice, and a server via a wireless communication channel. From step1140, the process proceeds to a displaying step 1150, where the displayassembly 130 displays a message. From step 1150, the process proceeds toend terminal 1160.
